Yeah, the android app could use some work. On the Asus transformer I have, the app crashes after turning a couple pages. I wound up finding where the app stores the base files, and open the issues in Adobe instead for reading. The issues are numbered like 106, 107, 108 etc.
It is too bad because I really like the feel of the Android app compared to the adobe reader.
I think the issues are stored in the Android\data\zymergy.com folder in the internal memory drive.
Good luck! Hope this helps!
